Q) Do I need STRAIGHT (Forward) or REVERSE NCR Paper?
A)  A quick test you can perform to determine which collation you need is, to number
three sheets of ordinary paper in order: 1 - 2 - 3. Load the numbered sheets so
that the printer prints on the same side that the numbers are on. Print the three sheets.
Take the three printed sheets from the output tray.
If the first sheet has a "1" on it, you need a STRAIGHT collated product.
If the first sheet has a "3" on it, you need a REVERSE collated product.

Q) Do you have this item available for a Dot Matrix Printer too?

A) YES, please check item item # P13
